Here is the triangle number 15: o o o o o o o o o o o o o o o To make triangle number 21 you add a row of 6 dots. Now you try! Prime Numbers A Prime Number only divides by 1 and itself. For example, 19 has only two factors, 1 and 19. Nothing else divides into 19. Here are the prime numbers up to 50: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 The Fibonacci Sequence 0 1 1 2 3 5 8 13 21 34 55 89 144 In the Fibonacci sequence, a number is obtained by adding up the previous two numbers, for example, (1) 13 = 5 + 8 (2) 55 = 21 + 34 When you have learned the number sequences, fill in the gaps in these sequences. 1 8 27 125 2 3 5 11 13 1 4 9 25 36 64 81 15 21 36 45 64 81 1 6 10 1 9 16 0 1 2 1 4 16 216 36 3 25 5 512 17 49 13 49 23 21 34 81
